112 PYROTECHNICS tion 4 parts potassium nitrate, 1 of charcoal, and 1 of sulfur has been reported in Chinese firecrackers; more recently mixtures containing both potassium nitrate and a small amount of potassium chlorate have been used; and at present, when the importation of firecrackers over 1% inches in length is practically 51 prohibited, flash powders containing aluminum and potassium FIGURE 37. Chinese Firecracker-*. Tying the Tubes into Bundles. (Courtesy Wallace Clark.) chlorate are commonly used, for they give a sharper explosion than black powder. The Chinese firecracker industry formerly centered in Canton but, since the Japanese occupation, has moved elsewhere, largely to French Indo-China and Macao in Portuguese territory. Its processes require great skill and manual dexterity, and have long been a secret and a mystery to Europeans. So far as we know, they had not been described in English print until Weingart's book 32 published an account of the manufacture of clayplugged crackers based upon information received from the manager of a fireworks company at Hong Kong. His account is illustrated with three pen sketches, two of them of workmen 51 Firecrackers not exceeding 1% inches in length and 5/16 inch in diameter carry a duty of 8 cents per pound. For longer crackers the duty is 25 cents per pound, which practically prohibits their importation. 52 Op. cit., pp. 166-170.
